Sir. How we check suction valave and delivery valve wether it correct working. after assembling.What is the special tool used for that purpose. Examiner asked.l told from a screwdriver. But he did not accept sir...🙏🙏🌻🌻
How to check.. You can do leak test after assembling valves. Once you install on place.. You can check the pressure gauge and check the pressure is building up as per the stage to check the working of valve. * Some makers give special tool for checking the valve after assembly... Usually v have to check the spring operation for free movement... Ur rt u can use screw driver to check the movement of spring after assembly
